ABSTRACT

The present invention provides hair care compositions comprising at least 10% of one or more polydialkylsiloxanes each having at least one pendant alkyl moiety, methods of using the compositions to reduce the loss of color in the hair, methods of using the compositions to reduce the effects of oxidation on the hair, and methods of using the compositions to add volume to the hair.

FIELD OF THE INVENTION

[0001] The present invention provides hair care compositions which canbe used to reduce color loss in hair, reduce the effects of oxidation ofhair, and/or add volume to hair.

BACKGROUND OF THE INVENTION

[0002] Hair is composed of keratinous fibers and is inclusive of headhair, eyebrows, eyelashes, mustache, beard, and other types of bodyhair.

[0003] Human hair is also commonly dyed with various coloring agents.Such hair coloring agents often fade with time due to washing or uponexposure to ultraviolet radiation from the sun.

[0004] Therefore, there is a need for a class of hair treatmentcompositions that enable longer-lasting color retention on the hair.

[0005] In addition, ultraviolet light from the sun or other chemicaltreatments, reduce the hair's mechanical strength due to oxidation ofthe hair components and causes fading of natural and applied hair color.Therefore, there is also need for a novel class of hair treatmentcompositions which provide superior protection from oxidative effects ofthe sun that compromise hair structure.

SUMMARY OF THE INVENTION

[0006] The present invention addresses the problems set forth above. Inone aspect, the present invention provides hair care compositionscontaining at least 10% by weight relative to the total weight of thecomposition of at least one polydialkylsiloxane having at least onependant alkyl moiety.

[0007] In another aspect of the invention, methods for reducing the lossof color in hair are provided.

[0008] In a further aspect of the invention, methods for reducing theeffects of oxidation on hair are provided.

[0009] In yet another aspect of the invention, methods for increasingthe volume of hair are provided.

DETAILED DESCRIPTION OF THE INVENTION

[0010] In accordance with the present invention, hair care compositionscomprising at least 10% by weight with respect to the total weight ofthe composition of at least one polydialkylsiloxane each having at leastone pendant alkyl moiety, which polydialkylsiloxane has a vapor pressureof at least 0.8 mmHg, and preferably at least 2 mmHg at 25° C. areprovided.

[0011] The compositions of the present invention comprise at least 10%of the polydialkylsiloxane including all ranges and subranges withinthis range such as, for example, at least 20%, at least 30%, at least40%, least 50%, at least 60 %, at least 70%, at least 80%, at least 90%and up to 100% by weight with respect to the total weight of thecomposition. The compositions may contain only one polydimethylsiloxanehaving at least one pendant alkyl moiety or they may comprise two ormore (that is, at least two) the polydimethylsiloxanes.

[0012] When preparing the compositions of the present inventioncontaining at least two of the polydimethylsiloxanes, thepolydialkylsiloxanes can be provided simultaneously or can be added atdifferent stages of production.

[0013] The pendant alkyl moiety is preferably a substituted orunsubstituted, branched or unbranched, alkane, alkene, alkyne, arylchain, or a mixture thereof. The alkyl moiety can contain from about 1carbon atom to about 50 carbon atoms, including from about 2 to about 30carbon atoms and further including from about 3 to about 20 carbonatoms. Preferably, the alkyl moiety contains from about 4 to about 16carbon atoms, and more preferably from about 5 to about 10 carbon atoms.In a preferred embodiment, the pendant alkyl moiety contains 6 carbonatoms.

[0014] When one of the pendant alkyl moieties is methyl, thepolydialkylsiloxane can be an alkyl methicone. Thus, alkyl methiconeshaving at least one pendant alkyl moiety as described above can besuitable polydialkylsiloxanes in accordance with the present invention.Preferably, the alkyl methicones are non-cyclic, linear methiconeshaving a molecular weight of less than 1000 and are volatile at roomtemperature . Preferred alkyl methicones include, for example, butylmethicone, pentyl methicone, hexyl methicone, heptyl methicone, octylmethicone, nonyl methicone, decyl methicone, cetyl methicone, laurylmethicone, and stearyl methicone, with hexyl methicone beingparticularly preferred.

[0015] According to one aspect of the present invention, thepolydialkylsiloxane having at least one pendant alkyl moiety has thefollowing structure:

[0016] wherein R₁ is an alkyl moiety, which can be a substituted orunsubstituted, branched or unbranched, alkane, alkene, alkyne, arylchain, or a mixture thereof. The alkyl moiety can contain from about 1carbon atom to about 50 carbon atoms, including from about 2 to about 30carbon atoms and further including from about 3 to about 20 carbonatoms. Preferably, the alkyl moiety contains from about 4 to about 16carbon atoms, and more preferably from about 5 to about 10 carbon atoms.In a preferred embodiment, the alkyl moiety contains 6 carbon atoms.

[0017] According to another aspect of the present invention, thepolydialkylsiloxane having at least one pendant alkyl moiety has thefollowing structure:

[0018] where R is hydrogen; or a branched or unbranched, substituted orunsubstituted alkyl group containing from about 1 to about 15 carbonatoms and z is from 1 to 5. The alkyl group can be an alkene, alkyne, oraryl group. In a preferred embodiment, R and z are selected such thatthe molecular weight of the compound is from about 300 to about 600. Inanother embodiment, the hydrocarbon-to-silicone ratio in the formulaabove is from about 0.25 to about 1.00.

[0019] According to one aspect of the present invention, thepolydialkylsiloxanes described herein are evaporativepolydialkylsiloxanes. One advantage of using such evaporativepolydialkylsiloxanes is that when they are applied to hair, they do notleave behind a greasy residue. As used herein in relation to thepolyalkylsiloxane, “evaporative” means having a significant vaporpressure under ambient conditions, which can be classified further asvolatile or near volatile. Volatile as used herein is a vapor pressureof at least 0.8 mmHg, preferably at least 2 mmHg at 25° C. andnear-volatile is having a vapor pressure of about 0.01 to about 0.14mmHg, more preferably from about 0.01 to about 0.10 mmHg, and mostpreferably from about 0.01 to about 0.05. Vapor pressure can be measuredaccording to methods commonly used in the art.

[0020] Examples of suitable polydialkylsiloxanes are hexylmethicone soldby Clariant Corporation under the product name SILCARE™ 41M10 (CAS#1873-90-1), caprylylmethicone sold by Clariant Corporation under theproduct name SILCARE™ 41M15 (CAS #17955-88-3), stearoxytrimethylsilanesold by Clariant Corporation under the product name SILCARE™ 1M71 (CAS#18748-98-6), octylmethicone sold under the product name SILSOST™ 034(Crompton and Knowles), hexylmethicone sold as DC2-1731 (Dow-Corning),and octylmethicone sold as DC2-1732 (Dow Corning).

[0021] The compositions according to the present invention can beformulated into, for example, shampoos, conditioners, hair treatmentcreams, styling gels, hair mousse, pump hair sprays, aerosol hairsprays, set lotions, blow styling lotions, hair color lotions, hairrelaxing compositions, permanent wave first agents, permanent wavesecond agents, and permanent color.

[0022] The compositions of the present invention can be formulated intoor with any cosmetically acceptable carrier or diluent. Examples of suchcarriers or diluents are water, alcohols, polyols, and oils such as, forexample, hydrocarbon oils and silicone oils. The carrier or diluent maybe present in amounts of 0% to about 90%, by weight with respect to thetotal weight of the composition, which is inclusive of numerals andfractions thereof with this range including 5%, 10%, 15%, 20%, 25%, 30%,35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, and 85%.

[0023] The compositions of the present invention may further compriseone or more components known for use in hair care compositions. Thesecomponents can be present in an amount of from about 0 to about 90% byweight with respect to the total weight of the composition, which isinclusive of numerals and fractions thereof with this range including0.01%, 0.1%, 0.5%, 1%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%,55%, 60%, 65%, 70%, 75%, 80%, 85% and 90%.

[0024] Examples of such components include surfactants that are suitablefor use on the hair or the skin. Suitable surfactants include anionicsurfactants, nonionic surfactants, amphoteric surfactants, zwitterionicsurfactants, or mixtures thereof. Surfactants useful in the inventioninclude those described in Kirk-Othmer, Encyclopedia of ChemicalTechnology (4^(th) Ed.), vol. 23, John Wiley and Sons, Inc., NY andInternational Cosmetic Ingredient Dictionary and Handbook (8^(th) Ed.)vol. 1-3 (2000), The Cosmetic, Toiletry and Fragrance Association,Washington, D.C. The surfactant can be selected for its cleansingproperty, foaming property, lathering property, emulsifying property orother desirable property.

[0025] Other examples include, but are not limited to, ultraviolet lightfilters, dyes, hair colorants, hair fixatives, hair waving agents, hairstraightening agents, organic solvents or diluents, foam boosters, pHadjusting agents, conditioning agents, humectants, lipids, fragrances,preservatives, proteins, protein derivatives, amino acids, amino acidderivatives, skin active agents, suspending agents, sunscreens,thickeners, vitamins, ceramide, uv absorbers (e.g., benzophenone),botanicals, anti-oxidants, retinoid, anti-dandruff, anti hair-loss andviscosity adjusting agents. These and other cosmetic additives commonlyused in hair care formulations are described in, for example,International Cosmetic Ingredient Dictionary and Handbook (7^(th) Ed.)vol. 1-3 (1997), The Cosmetic, Toiletry and Fragrance Association,Washington, D.C.

[0026] The compositions of the present invention can be prepared byusing various formulation and mixing methods commonly employed in theart to prepare hair care compositions, such as shampoos, conditioners,leave-in-treatments and/or hair coloring agents.

[0027] The compositions of the present invention are used by applying tothe hair before, during or after the hair has been colored or dyed. Thehair may be wet, dry or semi-dry. In the case where thepolydialkylsiloxanes are provided in a shampoo or conditioner, thecomposition may be used in a conventional manner for cleansing andconditioning the hair.

[0028] The compositions described herein can be applied to the hair byworking, rubbing, or massaging the composition into the hair so thatsubstantially all or some of the hair is contacted with the composition.In one embodiment where treatment for only a portion of the hair isneeded, the composition can be applied to the localized region asneeded.

[0029] According to one embodiment of the present invention, a method ofreducing color loss in hair comprising applying the hair carecomposition set forth above to the hair in an amount effective to reducecolor loss in the hair is provided. Preferably, the method is practicedon hair which is need of reduction of color loss.

[0030] “Reducing color loss” as used herein means a reduction in colorloss in hair relative to hair not treated with the compositionsdescribed herein. Color retention or color loss is within the skill ofthe art and can be measured using a chromometer, which is a procedurecommonly used in the art to measure color intensity of the hair (forexample, Berthuaume et al (1995), J. Soc. Cosmet. Chem. 46:231-245). Thehair is measured at one or more of the root, the middle, and the end ofa hair prior to treatment, serve as the baseline measurement. Next, thehair care composition is applied to half of the hair sample, e.g., halfa head of hair, while the other half is not treated. Then the entirehair sample, e.g., head, is shampooed and conditioned. Once dried, thechromometer measurement is repeated. By subtracting the end result fromthe baseline, a change in color intensity can be determined.

[0031] The inventors have also surprisingly discovered that applicationof the compositions set forth above provides an increased volume to thehair, for example head hair, when applied thereon. Accordingly, oneembodiment of the present invention is directed to methods of providingvolume to the hair (“volumizing”) comprising applying the hair carecomposition set forth above to the hair in an amount effective tovolumize the hair. Preferably, the method is practiced on hair which isin need of volumization.

[0032] An increase in hair volume or volumizing the hair is determinedas any visual increase in hair volume as assessed by the followingmethod. A part of a hair sample is treated with the polydialkylsiloxane,and another part is not so treated. The treated portion of the hair iscompared to the untreated hair for any visual increase in hair volume.

[0033] In another embodiment, the present invention provides methods ofreducing the effects of oxidation on the hair, such oxidation typicallycaused by the ultraviolet rays of the sun or by use of shampoos. Thereduction in oxidation can be effectuated by applying thepolydialkylsiloxane together with or separately from one or moreultraviolet light filters, UV absorbers and the like, which can bepresent in an amount to prevent damage to hair by UV light. Such amountsinclude, for example, from about 0.01% to about 1%, which is inclusiveof 0.05%, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9% and0.95%.

[0034] A review of physical blockers may be found at “Sun ProtectionEffect of Nonorganic Materials,” by S. Nakada & H. Konishi, FragranceJournal, Volume 15, pages 64-70 (1987), which is incorporated byreference herein.

[0035] It is well known that chemical absorbers are classified,depending on the type of radiation they protect against, as either UV-Aor UV-B absorbers. UV-A absorbers generally absorb radiation in the 320to 400 nm region of the ultraviolet spectrum. UV-A absorbers includeanthranilates, benzophenones, and dibenzoyl methanes. UV-B absorbersgenerally absorb radiation in the 280 to 320 nm region of theultraviolet spectrum. UV-B absorbers include p-aminobenzoic acidderivatives, camphor derivatives, cinnamates, and salicylates.

[0036] Classifying the chemical absorbers generally as UV-A or UV-Babsorbers is accepted within the industry. However, a more preciseclassification is one based upon the chemical properties of thesunscreens. There are eight major classifications of sunscreen chemicalproperties which are discussed at length in “Sunscreens—Development,Evaluation and Regulatory Aspects,” by N. Shaath et al., 2nd. Edition,pages 269-273, Marcel Dekker, Inc. (1997). This discussion, in itsentirety, is incorporated by reference herein.

[0037] The sunscreens which may be included in the present inventiontypically comprise chemical absorbers, but may also comprise physicalblockers. Exemplary sunscreens which may be formulated into thecompositions of the present invention are chemical absorbers such asp-aminobenzoic acid derivatives, anthranilates, benzophenones, camphorderivatives, cinnamic derivatives, dibenzoyl methanes, diphenylacrylatederivatives, salicylic derivatives, triazine derivatives, benzimidazolecompounds, bis-benzoazolyl derivatives, methylenebis-(hydroxyphenylbenzotriazole) compounds, the sunscreen polymers andsilicones, or mixtures thereof. These are variously described in U.S.Pat. Nos. 2,463,264, 4,367,390, 5,166,355 and 5,237,071 and inEP-0,863,145, EP-0,517,104, EP-0,570,838, EP-0,796,851, EP-0,775,698,EP-0,878,469, EP-0,933,376, EP-0,893,119, EP-0,669,323, GB-2,303,549,DE-1,972,184 and WO-93/04665, also expressly incorporated by reference.Also exemplary of the sunscreens which may be formulated into thecompositions of this invention are physical blockers such as ceriumoxides, chromium oxides, cobalt oxides, iron oxides, red petrolatum,silicone-treated titanium dioxide, titanium dioxide, zinc oxide, and/orzirconium oxide, or mixtures thereof.

[0092] The following Examples provide an illustration of embodiments ofthe invention and should not be construed to limit the scope of theinvention, which is set forth in the appended claims. In the followingExamples, all methods described are conventional unless otherwisespecified.

EXAMPLES

[0093] A total of 7 panelists with freshly colored hair were shampooed,conditioned, and then evaluated with a chromometer and compared to thechromometer values of untreated hair (ΔL values, where the higher thenumber, the greater the color loss). Hair stylists applied thetreatment, which was a 90/10 blend of hexyl methicones/ethanol to testzones on the panelist. These test zones were compared to shampoo andrinse-off conditioner controls. After 9 cycles the results were asfollows: Stylist applied color and then treated hair ΔL after ΔL afterPanelist¹ 4 cycles² 9 cycles² 1 (MC)-Test 1.6 1.8 Control 1.9 3.2 2(PKn)-Test 1.4 1.4 Control 1.7 2.7 3 (EK)-Test 0.9 1.6 Control 2.1 3.6 4(EP)-Test 2.4 2.7 Control 2.7 3.5

[0094] Interestingly, a significantly greater color loss was observed onthose consumers who self-applied color compared to the stylist-appliedcoloring products. In conjunction with the higher rates of color loss,the benefit observed was almost immediate.

[0095] Panelists self-applied color within 1 week prior to test followedby Stylist treatment ΔL after ΔL after Panelist 4 cycles¹ 7 cycles¹ 1(KR)-Test 2.2 4.8 Control 6.0 8.6 2 (LA)-Test 2.0 3.9 Control 3.4 5.7 3(PKa)-Test 4.2 5.0 Control 6.8 8.8

[0096] As illustrated in the tables, both expert and novice gradersnoticed a color-loss reduction when the difference between the twoproducts was greater than 1.3 units. Therefore, Hexyl Methicone providesa noticeable, meaningful, benefit.

[0097] In addition to the color protection effect, trained stylistsobserved a volumizing effect on the hair applied with hexyl methicones.The fullness of the hair was judged visually on a scale of 1 (very limp)to 5 (very full). On a half-head test, the side with the applied hexylmethicones was rated on the average of 3.6 while the control side wasrated as 2.2.

[0098] Obviously, numerous modifications and variations on the presentinvention are possible in light of the above teachings. It is thereforeto be understood that within the scope of the appended claims, theinvention may be practiced otherwise than as specifically describedherein.
